Question regarding structure PCD

Question regarding structure PCD

[jbrasen.qdt]

Hello,

   I was implementing support for PCDs in my platform using the new structure PCD support, and I had a question regarding this. Is it possible in the dec file to define the default values of a PCD defined as a structure using this format or just the byte array format?

Thanks,
Jeff Brasen

Jeff,

You can provide default values for structure fields
in the DEC file.

Liming has an example posted in the following branch:

https://github.com/lgao4/edk2/tree/UDK2018

DEC file example in TestPkg:

https://github.com/lgao4/edk2/blob/UDK2018/TestPkg/TestPkg.dec

Liming also posted a DEC spec (i.e. documentation) patch recently:

  [edk2] [Patch] DecSpecification: Add structure PCD definition syntax

It's upstream now and the rendered version can be seen here:

https://edk2-docs.gitbooks.io/edk-ii-dec-specification/content/3_edk_ii_dec_file_format/310_pcd_sections.html
